Please note !
Dependent on the number of battery /ies and inverter/s you are going to use – see your inverter user manual and/or inverter specifications , you may have a large amount of DC current coming from and running into your batteries – you may have to connect your + and – battery/ies leads and your inverter/s + and – battery leads directly to high current copper bus bars which we supply as a bus bar cabinet with integrated copper bus bars which are available for purchase under our circuit breakers and fuses section in our online store .
FREE ENERGY GENERATION : This product can be connected to our wind turbines we sell and is recommended as an alternative FREE WAY to generate energy as apposed to expensive generators which require costly fossil fuel that fluctuates and increases in price , are noisy and create fumes .
WIND TURBINES GENERATE POWER AT NIGHT and extends the life of your batteries significantly .
If you require generators for your solar OFF GRID SYSTEM , please see our list of generators we do sell for OFF GRID solar integration listed under our inverters section in our online store .
PLEASE NOTE :
All power system/s and or related products , including our State of the Art Geyser Wise heating systems we sell must conform to all local wiring regulations and standards. Genesis Power Systems Pty Ltd will not be held liable for any product damage and /or failure that could arise due to systems that have not been installed in accordance with the Manufacturers prescribed install method/s .
